In this case, It is preferable to carry out post-processing appropriately in accordance with the density of the natural fiber.

The porous sheet 23 _{1 is} formed of a flexible (including semi-rigid) polyurethane foam, a foam rubber and a nonwoven fabric. The porous sheet 23 ₁ has a thickness sufficient to accommodate the entire seedling in the porous sheet 23 ₁ For example, 3 to 10 mm. In this way, the thickness of the support base 22 ₁ is set to be extremely small with respect to the thickness of the porous sheet 23 _{1. In} Figs. 2 to 4, in order to clarify the structure of the breeding base sheet 21 ₁ , ₁ ) is drawn to exaggerate its thickness.

The width of the porous sheet 23 ₁ is set to be substantially the same as the width of the support 22 ₁ , but the porous sheet 23 ₁ is supported by the support 22 _{1 so} that the lower end thereof protrudes from the lower end of the support 22 ₁ , It adhered to, and the porous sheet storage recessed part (24 ₁ ...) is in the one surface of the support (22 ₁₎ so that the closed end supports (22 ₁₎ for receiving the seed of rice in the upper portion of seed, for example, be of the (23 ₁₎ As shown in Fig. Each of the recessed concave portions 24 ₁ ... is formed in a shape that regulates the posture of the seed rice stored in the storage recessed portion 24 ₁ substantially vertically or substantially horizontally. In this first embodiment, And is formed in an elliptical shape having a longitudinal length equal to or larger than the longitudinal diameter of the front end portion. Furthermore, each of the recessed concave portions 24 ₁ ... is arranged close to the upper end of the porous sheet 23 ₁ as in the first embodiment, or is opened at the upper end of the porous sheet 23 ₁ .

These slits 26 ₁ ... need only be capable of separating the porous sheet 23 ₁ by a plurality of sheet parts 25 ₁ ... and it is also possible to arrange the porous sheet 23 ₁ in the width direction, Or may be partially provided successively in the width direction of the porous sheet 23 ₁ .

In addition, the upper and lower portions of the supports (22 _1), the supports (22 _1), the longitudinal high-feed hooks for for sending a transfer hole as a unit (27 _1, ..., 27 _1, ...) are provided side by side in the respective line, The transfer holes 27 ₁ , 27 _1, ... are arranged substantially corresponding to the above-mentioned gaps 26 _1, .... And, a hole corresponding to the porous sheet (23 ₁₎ has a lower transfer hole (27 ₁ ...) which is provided in the lower portion of the supports (22 ₁₎ of ₍₁ ... 28) are respectively installed.

9 to 11) at the time of transit are formed in the lower portion of the porous sheets 23 ₁ ... at positions substantially corresponding to the respective accommodating concave portions 24 ₁ ... 29 ₁ ...) was provided, is provided in those hook hanger hole (29 ₁ ...) is in its lower portion is positioned on a lower side than the lower end of the support (22, ₁₎ a porous sheet (23 _1). Further, semicircular notches 30 ₁ ... Are provided on the lower end of the support 22 ₁ in correspondence with the upper portions of the hooking holes 29 ₁ ,.

The insertion of the shielding members 31 ... may be stopped by relatively increasing the width of the gap 26 _{1 in} the longitudinal direction of the porous sheet 23 ₁ and the sheet part facing the gap 26 ₁ when removing the continuous pores from the side of the 25 ₁₎ also it is possible to think, to prevent and also enters the sheet parts (25 ₁₎ adjacent sheet parts (25 _1), the roots of seedlings by growing the as such, the seedlings attached It is possible to simplify the feeding of the sheet component 25 ₁ .

As described above, in the production of the seedling sheet 21 ₁ , a step of producing a kneaded block made of a porous material having continuous pores and a step of slicing the block to a thickness of 3 to 10 mm to obtain the porous sheet 23 ₁ step, a support (22 ₁₎ and a porous sheet (23 ₁₎ for supporting a step, a bond with each other to be bonded to each other (22 ₁₎ and the housing recess to the punching process by the mold in the porous sheet (23 _1, 24 ₁ ..., the slits 26 ₁ ..., the holes 28 ₁ ... and the hooking holes 29 ₁ ... are formed in the porous sheet 23 ₁ and the transfer holes 27 ₁ ... 27 ₁ ... and the step of forming the notched portions 30 ₁ ... on the support base 22 ₁ are sequentially elapsed.

When a flexible polyurethane foam is selected as a porous material having continuous pores, it is possible to use polyols such as polyether polyol and polyester polyol and organic isocyanates such as phenylmethane diisocyanate of trirareness isocyanic acid 44 ' An amine catalyst such as triethylenediamine and the like, a tin catalyst such as dibutyltin dilaurate, a foaming agent such as silicone oil, a foaming agent such as H ₂ O and a low boiling point agent, And then completing the bridge to obtain a polyurethane foam. However, a coloring agent filler, a fertilizer and the like may be added as needed.

However, as described above, there are polyethylpolyol and polyesterpolyol as one of raw materials for producing a flexible polyurethane foam,_OneThe porous sheet 23_One), It is preferable to use a polyether polyol. This is because, in the case of using a polyester polyol, the number of independent pores is small and the air permeability is small, and the hydrolysis property is larger than that using the polyether polyol. If the density is less than 16 kg / m 3, the strength (particularly tensile strength and tearing strength) of the polyurethane foam is lowered so that the hook holes 29_One(Refer to Figs. 10 to 12) is hooked to the pawl hook 65 (see Figs. 10 to 12), and when the density is 35 kg / m < , The pore diameter becomes too small, and depending on the seedlings, germination and seedling growth may be disturbed. Therefore, the density of the polyurethane foam is preferably 16 to 35 kg / m < 3 > .

Here, in a practical production example of flexible polyurethane foam, 100 parts by weight of a polyether polyol having a molecular weight of 3000, a number of functional groups of 3 and OH of 56, 0.01 part by weight of triethylenediamine (amine catalyst) and 0.15 parts by weight of n- 0.12 parts by weight of dibutyltin dilaurate (tin catalyst), 5.5 parts by weight of water, 1.2 parts by weight of silicone oil (foaming agent) and 67 parts by weight of trilenediisocyanate (2.4 / 2.6 = 80/20) The mixture was stirred and foamed to obtain a flexible polyurethane foam. The physical properties of the obtained flexible polyurethane foam were a density of 18 kg / m 3, a tensile strength of 1.1 kg / cm 2, a tear strength of 0.62 kg / cm, and an elongation of 160%.

As a porous material having continuous pores, for example, when a nonwoven fabric is selected, long fibers such as polypropylene fibers and polyethylene fibers and short fibers are continuously spinned and entangled with each other, .

A block obtainable from a porous material having continuous pores in this manner is formed as a porous sheet 23 ₁ by slicing to a thickness of 3 to 10 mm by a slicing machine. In this embodiment, Is used.

When the support 22 ₁ and the porous sheet 23 ₁ are bonded to each other, for example, when the support 22 ₁ is made of polyethylene terephthalate and the porous sheet 23 ₁ is made of a soft polyurethane foam An acrylic resin pressure sensitive adhesive is applied to one side of the support base 22 ₁ and the porous sheet 23 ₁ by transfer using a doctor roll and then the both of the protrusions 22 ₁ and 23 ₁ are overlapped and pressed. In this case, it is preferable that not all the surfaces of the opposed surfaces of the supporter 22 ₁ and the porous sheet 23 ₁ are adhered but a part of the opposed surface is adhered to each other. By such partial bonding, the tensile strength of the porous sheet 23 ₁ is made larger than the peeling force of the porous sheet 23 ₁ by the pawl hooks 65 (see FIGS. 10 to 12) It is possible to reduce the force required for separating the sheet 23 ₁ from the support base 22 ₁ and to apply the force to the support base 22 _{1 when the} porous sheet 23 ₁ is peeled from the support base 22 ₁ it is possible to reduce the tensile force which, is the tensile strength to the support (22 ₁₎ required can be set relatively small.

In the punching process of the support table 22 ₁ and the porous sheet 23 ₁ by a mold frame, two processes of full curl and half-bulk curl are successively performed. First, in the entire curl process, a laminate in which the support base 21 ₁ and the porous sheet 23 ₁ are laminated is arranged so that the porous sheet 23 ₁ is located at the upper position, and the laminate is completely punched, The feed holes 27 ₁ ..., the hook holes 29 ₁ ..., and the semicircular notch portions 30 ₁ ... are formed. Subsequently, in the semi-split curling process, only the porous sheet 23 ₁ is punched by the separate knife-type member without curling the support 22 ₁ by the knife-like member, so that the storage recessed portions 24 ₁ ... and the slits 26 ₁ ... Is formed on the sheet 23 ₁ . After completion of the series of the production steps in this way, the breeding seedlings 21 ₁ are produced.

The hydroponic cultivation is used for seedling seedlings produced by the seedlingsheet 21 ₁ produced as described above. For example, in the seedlings of water supply, the seedlings are cultivated in the storage recesses 24 ₁ of the seedlingsheet 21 ₁ , Each next rice is stored. However, in seedling cultivation using the seedlingsheet 21 ₁ of the present invention, any of the seeds sown in water and the seedlings may be preceded by the seedlings dipped in water, For example, when seeding is first carried out and the seeds are immersed in water, the seed rice is stored at a relatively low temperature of about 15 c or lower, and the seed rice after sowing is stored in each of the storage recesses 24 ₁ , As shown in Fig. 5, the seedlingsheet 21 ₁ is wound in a roll shape to immerse the seed in water.

In this case, the porous sheet 23 ₁ is placed on the outer circumferential side so that the seedlingsheet 21 ₁ is rolled up and rolled up into rolled-up form, and the seedlingsheet 21 ₁ is heated for about 10 to 15 days Soak in water and let the seeds soak in water.

The seedling growing apparatus shown in Fig. 6 is used for germination promoting treatment after immersion in water. A seedling tank 35 is provided in a seedling chamber 34 in a seedlings house 33 constituted by a synthetic resin film or the like and the seedlings 35 wound in a roll shape on a lathe 36 provided on the bottom of the seedling tank 35 The sheets 21 ₁ ... are placed. It is preferable that the mountable shelf 36 is formed in a lattice shape so that the roots extending downward from the seedling sheet 21 ₁ placed thereon are not wrapped around each other.

The water circulation system 39 is constituted by the seedling tank 35, the circulation pump 37 and the heater 38 in this order so as to constitute the water circulation system 39 between the heater 38 and the seedling tank 35, Is disposed so as to be capable of spraying from the upper side to the seedlingsheets 21 _1, ... on the mountable shelf 36.

As shown in Fig. 7 (a), the seeds 41a are arranged upward and the seaweeds 41b are arranged on the storage recessed portions 24 ₁ of the seedlingsheet 21 ₁ , The seedlings 21 ₁ after being sown in a downward direction are placed on the mount shelf 36. The seedlings 21 ₁ are placed on the mount shelf 36 in a roll shape. Regulating the posture of the seed rice 41 is regulated by the fact that the young eyes 41c of the seeds 41a are laid flat or horizontally and the young seeds 41d are laid beneath or horizontally, It is easy to make the height of the seedlings.

Until the germination, the hydraulic fluid warmed at about 32 to 35 DEG C in accordance with the heating by the heater 38 is circulated in the water circulation system 39 to spray the hydraulic fluid from the spray shower device 40 at intervals of, for example, 5 to 8 hours. In this case, if the breeding seedlings 21 ₁ are immersed in the hydraulic fluid in the seedling growing tank 35, the germination is inhibited by the lack of oxygen. Therefore, Similarly, it is set at the level (L ₁ ) to keep the seedlingsheets 21 ₁ ... At 30 to 32 ° C in the air. Since light is not required until germination, the seedlings house 33 is shaded.

As shown in Fig. 7 (b), the cotyledon 41 / e grows upward from the seed rice 41 ... and flows downward from the seed rice 41 ... to the seed root 41f, .

The germinated seedlings 21 ₁ ... can be submerged in the hydraulic fluid and the level L ₂ corresponding to the lower portion of the seedlingsheet 21 ₁ , , And a level (L ₃ ) corresponding to the upper end of the seedlingsheet (21 ₁ ). When the liquid level is set below the level (L ₃ ), the hydraulic fluid is sucked up by the capillary phenomenon of the porous sheet (23 ₁ ) in the seedling sheet (21 ₁ ) It is preferable to spray water by the spray shower device 40 if necessary. Furthermore, since light is required after germination, the shading treatment of the seedlings house 33 is released.

After germination from all the seed rice is completed, the temperature in the seedlings house 33 is gradually lowered to about 20 캜 at the end of the seedling growing stage, and the humidity is gradually lowered to reach the wind. If you do so, you can grow a strong plant by preventing the seedlings from growing in vain. As shown in Fig. 7 (c), according to the seedling after germination, leaves up to the sixth leaf not shown in the figure are grown on the first leaf 41g and the second leaf 41h by the photosynthesis action or the like, The root 41f is elongated longer and the beard bill 41i grows from the root of the seed root 41f. It is preferable that the temperature, EC, pH and the like of the water-based liquid are automatically controlled at the time of seedling cultivation, and it is preferable that the water-based liquid is circulated and managed as the pH is easily changed.

After completion of germination, the seedlingsheet 21 ₁ is floated from the shelf 36 _one or two days before seeding, and seed roots 41f extending downward from the seedlings 21 _{1, 1} ) and the witch selection 36. The cutter 36 is provided with a cutter 36, When the seed roots 41f are cut and the seed coarse root is extended from the seed rice 41 ... after one to three days have elapsed, it is possible to obtain a good active attachment.

However, the purpose of immersing seed rice (41) in water is not only to absorb but also to dissolve germination inhibiting substances contained in the epidermis of seed rice (41) by dissolving in water, In order to melt, it is necessary to maintain proper temperature and humidity, and sufficient oxygen supply. The temperature during the period from germination to emergence is the most suitable from 30 to 32 ° C, and the germination is the fastest and the germination is also the best in such a temperature range. It is prone to be infected at a temperature lower than 30 to 32 ° C , And at a high temperature exceeding 30 to 32 캜, the absorption becomes strong, and the consumption of cesium (41 ₂ ) is accelerated, so that the seedlings grow strangely and unnecessarily, which makes it easy to become incense seedlings. As described above, it is possible to prevent the occurrence of both water shortage and oxygen deficiency which inhibits the growth of seed rice (41 ₁ ...) By seedling cultivation in the seedling growing apparatus using the seed growing sheet 21 ₁ , It is possible to dissolve the material in the hydraulic fluid and remove it, thereby promoting an even germination.

The results of comparing the germination rates of the present invention with those of the conventional method are as shown in FIG. 8, so that the germination rate can be increased as described above to enable uniform germination and emergence , And the growth after that is also excellent.

In addition, the seedlingsheet 21 ₁ is rolled into a roll shape and compactly integrated at the time of seedling cultivation, so that seedlings of a large number of seedlings can be seeded with the compact seedlingsheet 21 ₁ It is possible to reduce the space required for seedling growing. As shown in Fig. 9, compared with the conventional art, it is possible to greatly reduce the seedling growing area.

In Figs. 10 and 11, the seedlings cultivated by the seedlingsheet 21 ₁ are moved to the rice field by, for example, a two row webbing machine as a weaving machine. This machine has a mechanical frame 46 connected to a front end of a pair of substantially V-shaped knobs 45, 45, and the mechanical frame 46 is fastened with a hook 47. An engine 48 is mounted on a mechanical frame 46 extending in front of an upper portion of a float 47. A transmission for transmitting power from the engine 48 is mounted on a transmission case 49 Is extended to the machine frame 46 extending forward and backward on the rich portion 49 so as to extend rearward from the engine 48. Further, rotary shafts 50 and 50 protrude from both ends in the front-rear direction intermediate portion of the transmission case 49, and wheels 51 and 51 are attached to the ends of the rotary shafts 50 and 50, respectively. The power from the engine 48 is transmitted to the two rotary shafts 50, 50, that is, the wheels 51, 51.

In the sheaths of the both handles 45 and 45, a transfer stand 52 ₁ for placing a pair of seedlings 21 ₁ and 21 ₁ wound in a roll shape and subjected to seedling treatment is provided.
